touched down in las vegas in the battleground state of nevada. the president is expected to come down those stairs at any moment. the campaign -- a day after witnessing the devastation of hurricane sandy and just five days before the election, nevada will be the second of three stops today for the president, which began in wisconsin and will ultimately end in colorado. and here with a preview of the last days of campaigning is nbc's kristin welker who is awaiting the president in las vegas. kristin, we've been hearing some conservatives complain about the president's excellent working relationship with republican new jersey governor chris christie in the aftermath of the storm. how is the white house handling those complaints? >> well, martin, good afternoon. the white house publicly is saying they're not going to comment on the complaints or the president's visit really, what it could mean politically, because they say this is not a time for politics. i can tell you privately though that both democrats and republicans were a little bit surprised by governor christie's tone yesterday.
